The Secret of Live | Suspenseful reasoning

Harada, a police officer, received a report that a female body had been found in Half Moon Lake that morning.

　　

　　Harada brought people to the scene, and after investigation, the deceased's name was Yumiko, 22 years old, a bank employee, and social relations were simple. She died between 8 and 9 p.m. last night and was due to drowning. Police on-site investigation found that the deceased had a mobile phone in her satchel and one of her shoes left in the grass on the shore.

　　After returning to the police station, the Technical Department repaired the deceased's mobile phone data and found that the deceased had called a man named Ichiro Miyazawa at 8 o'clock last night, but it was not connected. The police also judged from the text message records of the two that Miyazawa Ichiro was Miko's boyfriend, and the relationship between the two was very stiff some time ago, and they were only reconciled recently. Harada groaned a little, feeling the need to meet Miyazawa ichiro first.

　　Miyazawa lived in an apartment more than a dozen kilometers away from Lake Half Moon, and harada was sleeping when he arrived with the police. Shocked to learn of Yumiko's murder, he said that they were planning to get married at the end of the year a few days ago. Sensing that the police seemed to be the prime suspect, Miyazawa excitedly said that he had been broadcasting live at home last night and had not walked out of the house for half a step all night.

　　It turned out that Miyazawa had recently been working on live streaming, broadcasting live at home every Tuesday night, and yesterday was exactly Tuesday. If Miyazawa hadn't lied, he did have an alibi.

　　Harada looked around miyazawa's house and asked, "In which room did you broadcast it live, can you show me it?" ”

　　Miyazawa did not hesitate to lead Harada into a room with various shooting equipment, several shelves filled with various products, and a display table in front of the tripod where the machine was erected, and several boxes of milk powder on the countertop. There was a window on the wall opposite the tripod, and looking out from the window, there was a huge LED billboard hanging outside the tall building opposite.

　　Harada asked, "Haven't you ever left here during the live broadcast?" Miyazawa said: "I went to the toilet halfway and left for about 5 minutes, and my stomach was uncomfortable. ”

　　"What time is it?"

　　"Around 9 o'clock." Miyazawa scratched his head, "I didn't pay attention to the specific time." ”

　　Harada frowned slightly, this time is almost the same as the time when Yumiko was killed, is it a coincidence? He asked, "The deceased called you once at 8 o'clock, but you didn't answer it?" ”

　　"This..." Miyazawa looked remorseful, "in order not to affect the live broadcast, I blocked all incoming calls, I knew that such a thing would happen, and I would not set it up to death." Speaking of this, Miyazawa pounded his head with his hand in chagrin.

　　"Do you know what happened to the other person calling you?"

　　"I don't know!" Miyazawa shook his head, "The last time we met was last weekend, and she was busy these two days, so we didn't date." ”

　　Harada nodded, "Can you provide your live account?" ”

　　"No problem!" Miyazawa was very cooperative and reported his account on the spot.

　　Back at the police station, Harada followed Ichiro Miyazawa's live account and found what last night's live video looked like. In the video, the system time shows that the live broadcast starts at 7:30 p.m. Miyazawa sold adult milk powder last night, which explains why there are several boxes of milk powder in his live broadcast room. At the beginning of the live broadcast, Miyazawa, wearing a black coat, sat in front of the camera energetically, and there was a rainstorm in the city that afternoon, and Miyazawa took this rainstorm as the opening statement to remind fans to pay attention to the weather and pay attention to health, and then he picked up a can of milk powder and explained it. The popularity of Miyazawa's live broadcast room is very strong, and there are constantly people sending bullet screens to consult various questions, Miyazawa is very patient, and he has selected several questions to give answers, even if it is a simple question, he has answered it in detail. When the live broadcast was carried out at 8:30, some fans sent a bullet screen to remind Miyazawa to drink water, Miyazawa did look a little dry mouth, saw the bullet behind the scenes said "thank you", picked up the water cup and drank water. After 10 minutes, he suddenly covered his stomach and looked uncomfortable, he got up and went to the bathroom and left for about five minutes. After returning to the live room, he seemed to be dissatisfied with the camera, walked to the tripod and adjusted it before continuing the live broadcast, and then he kept demonstrating various ways to eat the milk powder, and the live broadcast ended at about 11 o'clock.

　　Harada noticed that when Miyazawa adjusted his tripod, the camera swept through the window, and the view from the window was the same as what Harada had seen at the window of Miyazawa's house that day—the huge LED billboard was impressive. In this way, the possibility of Miyazawa "cloning" a live broadcast room near Half Moon Lake is also ruled out. Miyazawa did broadcast live at home, he lived more than ten kilometers away from Half Moon Lake, the fastest round trip on the road is 20 minutes, he can hardly travel between the two places in 5 minutes and commit murder.

　　Miyazawa's suspicions seem to have been lifted, but Harada always felt that something was wrong.

　　The next morning, While eating breakfast at home, Harada turned on the live video, intending to find clues again. The wife looked at it curiously and said, "Are you watching the live broadcast?" This milk powder seller can really pick the time, early in the morning to open the live broadcast ..."

　　"Pick the time"... His wife's words made Harada's eyes light up: the location of Miyazawa's live broadcast seems to have no flaws, but is there any hands and feet on the live broadcast time? Harada stared at the live broadcast...

　　In the afternoon, Harada took Miyazawa to the police station and told him that Yumiko's case had been solved. Miyazawa was surprised and asked who the murderer was. Harada looked directly at him and said, "Isn't that you?" ”

　　Miyazawa was stunned, then laughed, "Officer, don't you kid yourself, I have an alibi, don't you?" ”

　　"Your 'alibi' is probably a self-directed play!" Harada said, "On the day of the crime, you invited Yumiko to meet at Lake Half Moon, and when she was not ready, you pushed her into the lake, and created the illusion that she accidentally fell into the water." In order to eliminate suspicion, you specially chose the time of the crime at 8 pm on Tuesday, because this is the time of your weekly live broadcast, which is also your strongest alibi. You recorded the video in advance and did technical processing to ensure that the live broadcast could go on as usual, in order not to show your feet, you deliberately took a shot of drinking water after listening to the audience's suggestions, and there was a session to answer the audience's questions, creating the illusion of "real-time interaction". The five minutes of going to the bathroom and leaving should be a trap deliberately designed by you to lead the police to suspect that you sneaked out to commit the crime, but you also borrowed the debugging camera to deliberately leave clues for the police, naturally self-confessing, and avoiding the possibility of further suspicion. ”

　　Miyazawa's face began to ooze fine beads of sweat, Harada continued to "attack", he speculated that a rainstorm on Tuesday afternoon gave Miyazawa a new inspiration, in order to make the recording look more like the day's live broadcast, Miyazawa re-filmed the opening scene with the rainstorm as the opening statement, which made him go out a little later. At 8 o'clock, Yumiko saw that Miyazawa had not arrived, so she called, Miyazawa did not answer, and then he hurried to arrive, taking advantage of Yumiko's lack of attention and quietly moved. During this time, Yumiko struggles and leaves a shoe in the grass, which Miyazawa does not notice. After the murder, Miyazawa used an anonymous account to enter his live broadcast room and sent a bullet screen at 8:30 on time, reminding the anchor to drink water in a fan tone... All of this worked so seamlessly that it was mistaken for the live broadcast that night.

　　Miyazawa let out a string of contemptuous laughter: "I didn't expect Officer Harada to be a master of stories, this story is quite wonderful!" ”

　　"Make up a story?" Harada seemed to be prepared, he turned on the computer, and fast-forwarded the live broadcast screen: "This is the picture of your official live broadcast, and your sleeves are clean and tidy at this time." After Harada finished speaking, he pulled the picture to the end of the pause, pointed to a stain on Miyazawa's left cuff in the picture, and said: "This is the sleeve accidentally touched by the spoon when you demonstrated the milk powder eating method before the end of the live broadcast." After Harada finished speaking, he dragged the picture again, pointed to the cuffs that were also stained with milk stains in the picture, and said: "This is the opening screen of the night, when you mentioned the rainstorm, you can be sure that the start video was filmed on Tuesday, and the strange thing is that at this time, you actually have the same milk stains on the cuffs." Milk stains in the middle of the live broadcast are unlikely to appear in the opening screen in advance... Do you still need an explanation? ”

　　The corners of Miyazawa's mouth trembled slightly, and Harada pressed forward step by step: "We also found the 'fan' who reminded you to drink water, the registered IP is in your apartment, and the last login is Tuesday night at 8:25..."

　　"Enough, I, I'll give it all!" Miyazawa's face was miserable, in front of the evidence, he finally admitted that he had come together with the other party because he coveted Yumiko's money, and then he wanted to break up after squandering it, Yumiko refused, and in anger, he had the intention of killing...
